How cotton swabs are made

Cotton swabs began when a man watched his wife wrap cotton around toothpicks to clean their baby's ears.

The short version

Sticks of rolled paper, plastic or wood are dropped into clips on a moving conveyor. Adhesive goes on the ends, a measured wad of cotton from a coil is attached, and a shaper moving at a different speed from the conveyor rolls the wad into a firm tip. High-speed lines then count the finished swabs into boxes.

Make the sticks

Plastic stems are injection molded or extruded in thin rods from polypropylene or polyethylene. Paper stems are rolled or wrapped into a rigid tube, a more common choice since bans on plastic stems began.

Paper Polypropylene
Prepare the cotton

After ginning and carding to align the fibers, the cotton arrives at the factory as loose fiber or a coil of cotton wool.

Raw cotton
Load the conveyor

Individual sticks are deposited on a continuously moving belt or chain, where clips hold each one.
Glue the ends

An applicator puts adhesive on one or both ends of each stick.

Adhesive
Attach and shape the tip

A portion of cotton coil sticks to the glued end. A shaper bar or belt, moving at a different speed than the conveyor, rolls it against its surface and forms a tight tip under tension.
Check and box

Automated lines look over the tips, then count and pack them. Double-tipped swabs get the same treatment at each end in sequence.

Worth repeating

Leo Gerstenzang developed the first mass-produced swab in 1923 after watching his wife wrap cotton on toothpicks.
The earliest name was Baby Gays, changed to Q-Tips Baby Gays in 1926, where Q stands for quality.
A wooden handle and a paper sleeve let a medical swab be sterilized in an autoclave.
